Hi I just got this emulator to try it out but when I open it it says Unable to Find BIOS....thing is I do have the bios and its on the data folder. On the Readme it says to take out the extension from the file see if it fixes but no luck..
have you named the files dc_boot.bin and dc_flash.bin? If not then try renaming the file to that. The only other explanation is that the bios files may be either completely corrupt or not containing all the data.
